4AGE - Small porting a big port head.

[Stealer Of Souls]

I remember seeing that someone had done this...
Who was it?
How do you do it?
Who would I get to do it?
Is it worth it for a street driven NA AE85.5 with little or no mods?
Was thinking of running TVIS this time around since I street my car 80% of the time. What would be the effect of small porting only one of the ports? Butterflied port? Non-butterflied port? Not worth it? Educated guesses anyone?

redmist has the small ported bigport head i think. I would think its only something you want to do for a race engine. I dont think the resin used lasts forever

just buy a small port head
the head has 4 ports and its the manifold that has 8

I didn't think the TVIS manifold bolted up to the small port head very well (ports don't line up properly)?

[Drifter4ag]

do a cut and shut

i got a big port cut n shut manifold sitting here if someone wants to buy
